The industry has marketed “wax, hot wax, polish wax, sealer wax” etc. in car washes for many decades since the 1950’s. These products are and always have been widely advertised and understood to be quick, short term finish enhancers and took there names from the hand applied detail shop services of the time. They are priced that way too - generally a few dollars, compared to the $75 or $100 and up these services would cost in a detail shop.
The current ”ceramics” are just the latest trend in terminology that is in alignment with the automobile finish industry that the car washes have latched onto - as they have for decades. I do not feel as though I am tricking customers with the terminology or names. Many of the merchandising materials for the car wash products advertise “two week” or “up to 30 days” of protection, whereas the detail shops that charge hundreds for these coatings advertise “two years of protection ” or “ never wax your car again”.
The claims are very different and the pricing and descriptions reflect their differences.
When I buy a hamburger that is 100% beef, I know I am still not getting a filet mignon - even though it is still all beef. And the price reflects that too!
